STM32 MCUs Products

HI I'm using stm32h753. I'm wondering how I can get access to user SRAM and declare an array there.

I already have a STM32H735G-DK board for the workshop on 25th March.

Change Pin mode from analog to digital in run time. See my code below..

I want to use pin to work as output pin for some time and then Analog pin for some time.how can I change the mode of pin in run time. GPIO_InitTypeDef GPIO_InitStruct = {0}; ADC_ChannelConfTypeDef sConfig = {0};   HAL_GPIO_WritePin(GPIOC, GPIO_PIN_...

There is a need to interact with the 3-pin MediaLB bus.

Hey!There is a need to interact with the 3-pin MediaLB bus.I cannot penetrate into it.How the data exchange takes place, what conditions must be observed, how the request and return frame is formed.Perhaps there are examples of working with the bus o...

SPI modes unclear

Hi everyone,I am working with the SPI in slave mode on an STM32G071 and having some trouble with the different SPI modes. I set both CPOL and CPHA to 0 during initialization: SPI_InitStruct.TransferDirection = LL_SPI_FULL_DUPLEX; SPI_InitStruct.Mode...

I ordered the board from the distributor

What is the default value for PLLON ? If it is 0, should I put a while(PLLRDY =1）?

I have an application running on HSE as system clock..and I set the multiplexer to select HSE, totally not using PLLbtw, should I put any configuration to my PLL? such as PLLON =0, and while(PLLRDY==1) , to “properly configure�? the unused PLL?Or sho...

STM32G071 write protection, bricked MCU flash

Hello, MCU bricked after I tried to remove write protection. Now when I read the flash it shows only 0xFFFF0080. Read the full description bellow. We are making new project using STM32G071.We use serial communication custom bootloader so we can updat...
